A mounting assembly for an injector is located in a curved portion of an exhaust line having an exhaust flow from an upstream end to a downstream end. The mounting assembly includes an indent extending at least partially into the exhaust line curved portion and disposed in the exhaust flow. The downstream wall has an interior surface oriented to substantially face the exhaust line downstream end. A recess extends from the downstream wall in a direction away from the exhaust line downstream end, and a recess aperture is formed in the recess and configured to fluidly communicate with the injector. The recess reduces the amount of exhaust heat reaching the injector tip.
